The MMIQ device is need to create a human-machine interface system (HMI) programmable using the development environment Qpaint.
The device provides a range of information on the interface panel with a speed of update can be set by means of the sampling time.
In the configuration unit, in the BUS section, must be declared an instrument whose firmware contains the MMIQ device.
In the INTDEVICE section must be add the following definition:
;--------------------------------- ; Internal device declaration ;--------------------------------- INTDEVICE <device name> MMIQ TCamp
where:
| <device name> | The name assigned to the device. |
| MMIQ | Keyword that identifies the device. |
| Tcamp | Time sampling device (1÷10 ms). |
;-------------------------------- ; Internal device declaration ;-------------------------------- INTDEVICE DEV MMIQ 0001
The key and keyf parameters are used to recognise which key was pressed. The values associated with each key are given in the chapter of this manual “Commands and parameters”.
Any bit of the key and keyf parameters is associated with a button, so if you want to determine the pressing of several keys it helps to check that these parameters assume a value equal to the sum of the values associated with the keys.
The leds and blinkleds parameters are used to access (or flashing) and turn off the leds on the keyboard.
Normally there is one led for each function key.
To access (or flashing) and turn off the led you must assign to the code associated with the function key.
Every bit of the leds and blinkleds parameters is associated with an led.
The name of the parameter, state or command is shown at the left of the table.
R
Indicates if the parameter or state is retentive (upon initialization of the device maintains the previously defined state), or the state assumes upon initialization of the device.
If the device does not need to initialize the “R” field indicates the value that the parameter or state take to the power on of the card.
R = Retentive
0 = Upon initialization of the device the value is forced to zero.
1 = Upon initialization of the device the value is forced to one.
- = Upon initialization of the device is presented significant value.
D
Indicates the size of the parameter.
F = Flag
B = Byte
W = Word
L = Long
S = Single Float
Are described all the conditions that must exist is considered correct or because the command is accepted.
In some cases, limit values are specified for the acceptance of the parameter: If there are any values outside the limits set, the data is in any case accepted; therefore appropriate controls of the application must be provided to ensure the proper functioning.
To run a command, all conditions must be met; otherwise the command is not sent.
A
Indicates the access mode.
R = Read.
W = Write.
R-W= Read / Write.

| Nome | D | R | A | Condizioni | Descrizione |
|---|---|---|---|---|---|
| leds | L | 0 | R-W | - | Leds status Parametro utilizzato per accendere i LED dei tasti funzione. Ogni bit del parametro è associato un LED. Per il valore associato al parametro keyf. |
| blinkleds | L | 0 | R-W | - | Blink Leds status Parametro utilizzato per far lampeggiare i LED dei tasti funzione. Ogni bit del parametro è associato un LED. Per il valore associato al parametro keyf. N.B. Perché un led possa lampeggiare è necessario associare il valore relativo a quel led sia al parametro leds che al parametro blinkleds. |
